Revert "Disallow setting default on internal network"

The original patch assumes that both --external and --is-default are set
in the same request and broke case when --is-default is set as an
network update. The validation logic have to be moved on API side to
avoid extra API calls from openstackclient.

This reverts commit 962efd9.
